SIT Tech. Workshop 2014 CNES, Montpellier, France 17 th -18 th September Background Why a VC/WG Day? A request was put forward during SIT Chair Tag up Telecons with VCs and WGs held in January-February to hold a dedicated Virtual Constellations Day back-to-back the SIT Technical Workshop Preliminary discussions about the possible content of this VC Day led immediately to identify the need to involve the Working Groups at all levels in its planning and organization Further discussions took place during the second series of SIT Chair Tag up Telecons with VCs and WGs in June-July These discussions confirmed the interest to hold this special event and agreed on the format and topics for the VC/WG Day

SIT Tech. Workshop 2014 CNES, Montpellier, France 17 th -18 th September Quick summary of the discussion Topic #1 – CEOS-SIT-VC-WG interactions in terms of support needed and/or offered; CEOS promotion of VC/WG achievements Each VC introduced itself in ~2 minutes with ~2 slides. The discussion emphasized the importance of face-to-face meetings For CEOS to achieve greater success, and building on the success of this first workshop, an immediate recommendation to CEOS and SIT was to hold annually a VC/WG Day organized and led by the VC/WG leaders Topic #2 – Training Activities This was the very first occasion for the WGCapD to meet the VCs. The discussion built on past examples of training activities settled out by VCs. Opportunities for “thematic” training workshops (e.g. SST + OCR, air quality, volcanic ash/disasters) making use of inputs from several VCs were considered. An immediate recommendation was that each VC should have a point-of-contact with WGCapD (and other WWGs as well)
